I’m really not sure what to do to enable RDP from outside of my home network. I have a reasonably good Linksys router. I’ve been doing some reading up about it but:…

1. How would I set-up/configure port forwarding?
2. Would I configure my router with the static IP information provided and if so how would I point any incoming traffic to my domain controller?
3. What sort of Firewall do I need? Should I buy one or is it built into the router?
4. Any security considerations, I’ve looked into VPN’s and I understand that they’re more secure but I have to be able to connect to this environment and as RDP comes as standard I would prefer to utilize it in the first instance.

Any advice/links would be greatly appreciated.

I donot understand that how static routing is more secure than dynamic routing?

My other question is that in static routing ,what we do is simply enter the information regarding the neighbouring Router in the routing table of our Router ,but if the remote network connected to the neighbouring Router fails or if any route in the routing table of the neighbouring Router gets down, then does this Router automatically informs our Router about this route or network failure or we have to manually update the routing table of our Router with it?

I hope my question is clear
